GAS-BURNER.

Patented Mar. 24, 1914. ser-iai No. 786,927'.

To all 'zo/tom it may conce/m.'A

Be it known that we, LOUIS STooKs'rRoM and HERMAN H. PARPERT, citizens of the United States, residing at St. Louis, 1n the Stato of Missouri, have invented certain new and useful Improvements in Gas-Burners, of which the followingl is a specification, reference being had therein to the accompanyingdrawing. y

Our invention relates to improvements 1n gas burners. l

The object of our invention isto provide a burner in which the air and gas is more thoroughly mixed and yat the same time absolutely preventing the flame from Workingliack and burning in the mixing chamber.

Another object of our invention 1s to provide a simple, cheap and more effect-ive burner having certain details of structure4 and operation hereinafter more fully lset fulth.

In the accompanying drawings-Figure 1 is ay perspective view of our improved burner showing the outer casing partly broken away. Fig. 2 is a Vertical transverse vsectional view of our improved burner.

Our improved burner is more particularly designed to be used on automatic Water heaters and consists of a combined air and gas the enlarged mouth portion 2, which is provided with the gas supply pipe 8, and around this gas supply pipe is arranged a shutter of the usual form by means of which the amount of air passing into the tube may be readily controlled. The outer end of the tube l'is provided' with an enlarged rectangular shaped mixing tube 4,' havingin its sides the horizontally arranged slots 5, extending along the entire side thereof and aroundV the ends a short distance, as clearly shownv in Fig. 1 of the drawings. These vslots are comparatively close .together and allow the escape of the air and gas from chamber 4.

The mixing chamber 4:,.at its lower end, is provided with a flange G entirely encircling the same and said flange at the ends is provided with ears 7, the purpose of which will -be hereinafter more fully described.

.Surrounding the Hanne 6, ad'aeentI its outer .es n edge is a shoulder 8, and resting upon the flange beyond the said shoulder is a housing 9 of rectangular form, and spaced a short distance from the mixing chamber 4, leaving the mixing .the mixing chamber and passing through the ears 7 and 11 are@l bolts "12, whereby the housing is clamped t-o the flange and `firmly held thereto. The upperend of the housing 9 is drawn inwardly at 13, and said inwardly drawn portion is provided with opening 14, entirely around ,the housing. r1`he housing 9, above t-he inwardly dra-wn portion 13, is provided .with .a flange 15, which forms a receptacle or pocket 16, which is adapted to retain any of the dripping from the coils of the burner and preventit from running down into the openings 13 to the space 10 *between the mixing chamber 4 'and the housing 9.

As heretofore stated, thev gas is supplied vthrough the pipe 3 to the tube 1, and at the same time air is drawn int-o the enlarged portion 2 of the tube and enters the mixing chamber 4. The air'and gas is thoroughly mixed within this chamber and passes through the horizontal slots into the space 10 between the mixing chamber and *the housing 9. The mixture then passes upwardly through the space 10 and out through the openings 14 and burns at these points.

From this description it willv be seen that the air and gas is more thoroughly mixed and the openings 14.- arc small enough to prevent the flame from burning within the space 10 on the outside of the mixing tube. The horizontally arranged slots 5 are also small enough to absolutely prevent the flame from burning in the mixing chamber 4, should itpossihly .work its way down into the space 10 between 'the mixing chamber and the housing 9. The housing E) prevents any deposit or liquid from ei'igaging the mixing chamber and cloggingthe horizontally .arranged slots and the flange 15, carried by the upper end of the housing, catches and retains any drip from the coils of the heater.

Having thus described our invention, what we claim and desire 'to secure by lLetters Patent isl. A burner comprising a mixing chamber, a combinedy air and gas supply for said chamber, a removable housing surrounding and spaced therefrom, and av gas discharge opening atthe upper end of the housing above the mixing chamber.

2. A burner comprising a mixing chamber having horizontally arranged slots, a combined air and gas supply for said mixing chamber, a housing surrounding the mixing chamber and spaced therefrom, and discharge openings in the upper end of the housing abovethe mixing chamber.

A burner comprising a mixingchamber, having horizontally arranged slots, a combined air and gas supply for said mixving chamber, a housing surrounding the mixing chamber and spaced therefrom, said housing having discharge openings above the mixing chamber, and a drip-pan formed inthe upper end of the housing, substantially as shown and described.

4t. A burner comprising a mixing chamber, having horizontally arranged slots in `its sides and extending partially across the ends, a combined air and gas supply for said mixing chamber, a. flange carried by the lower end of the mixing chamber, a-housing supported by said flange and spaced 'from themixing chamber and entirely inclosing the same, and said housing having discharge openings at its upper end.

5. A ,gas burner comprising a ,mixing chamber, having horizontally arranged slots in its sides and extending partially across the end thereof, a combined air and gas supply for the mixing chamber, a flange' carried yby the lower'. end of the mixing chamber,

ing ears at its ends, a housing resting upon the flange and surrounding the mixing chamber, ears carried by the housing and correspending Ato the ears carried by the fla-nge, bolts passing through the ears of the housing and flange, said housing having an inwardly drawn upper end provided with openings entirely around the same, and said housing having an upwardly extending flange inside of the said openings and forming a drip-pan.

7. A burner comprising i.a mixing chamber of an elongated form and having horizontally arranged slots in two opposite sides, a combined air and Gas supply for the lower end of the mixing chamber, a flange carried by the lower end of the mixing chanibe' and having a thickened portion forming a ledge entirely surrounding the mixing chamber, cars carried by the flange on opposite ends, a housing resting upon the flange on the outside and abutting the ledge and surrounding the mixing chamber, ears carried by the housing and corresponding to the ears carried by the fiange, and means carried by the ears for securing the housing to the mixing chamber, said housing having its upper end drawn inwardly and provided with openings entirely around the same and said housing 'having an upwardly extending flange on the inside of the said openings and forming a drip pan.

8. A burner comprising a combined air and gas supply, an enlarged mixing chamber formed integral therewith at its outer end, said mixing chamber having openings in opposite sides, a flange carried by the lower end oi the mixing chamber at the point of junction of the mixing chamber and air and gas supply, and a housing surrounding the mixing` chamber and space therefrom and supported `and secured to the flange and said housing having discharge openings in the upper end thereof above the mixing chamber.

9. A burner comprising a mixing chamber having openings therein` a combined air and gas supplyfor said mixing chamber, a housing surrounding the mixing chamber and spaced therefrom, said housing having discharge openings above the mixing chamber, anda drip pan formed in the upper end of the housing, substantially asshown and described.

In testimony whereof we hereunto affix our signatures in the presence of two witnesses.
